is a stable of sumo wrestlers, part of the Dewanoumi or group of stables. It was set up in 1990 by former Tochiazuma Tomoyori, who branched off from Kasugano stable. He coached his son, who also wrestled under the name Tochiazuma, to ōzeki rank. Tamanoi reached retirement age in September 2009, and was succeeded by his son.
As of May 2026, the stable has 24 active wrestlers.
The stable is based in Nishiarai in Tokyo's Adachi ward, and built new premises in 2004, 10 minutes from the old location. In December 2011 Tamanoi and wrestlers from the stable assisted the police by starting street crime prevention patrols in the local area in the run up to the New Year celebrations.
In September 2020 nineteen members of the stable tested positive for COVID-19, after a lower ranked wrestler became ill. Every wrestler at the stable was prevented from participating in the September tournament.
Ring name conventions Many wrestlers at this stable have taken ring names or that include the character 東 (read: or ) meaning east, in deference to their coach and the stable's owner, the former Tochiazuma, as well as his father, the founder. It can also be used as a prefix, as in Azumaryū and Azumasato, as well as a suffix as in Yoshiazuma and Fujiazuma.
